Y Application le'd December 10, 1923. Serial No. 679,673;

My invention relates to improvements in mattress filling mech anisms, andparticularly to a device adapted :tor till-ing; mattresses having inner tulting or compartments or' scctions therein, the filling material bein-g inserted after the tnfting oat the mattress is already madeor the compartments formed.

The invention has amon-gitsobjects the production Volf an apparatus of the kind described Which isV sim-pla, compact, durable, etiicient and satis-factory for use Wherever 'found applicable.-

It has particularly as an object the production of a mattress making machine ofL the kindV described that will be rapid in operationy and Will. yoperate Without injury or stretching of the mattress ticking or covering when filling-Y inner tufted' or compartment mattresses.

Many other` objects and advantages of" the construction herein shown' and described will bel obvious to those skilled inv the art from the disclosures herein given.

To this end myinvention consists in the novel construction?, arrangement and combination of parts herein shorvnand described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indica-te like or correspond-ing parts:`

Fig. 7 is a section taken substantially on line 7 7v ofFig. 6;.

Fig. 9 showsa modified form ot device.

Referring to the drawings, ly indicates a tablev ot any suitable size and height and lThe mattress coveror tick 2 consists ot the usual taken substantially on box-shaped bag or casing,l in which rupper preferably at intervals so as to provide any inner tutt-ing; or thesesheets may be. connected together by partiti-ons, form-ing compartments Obviously, the Whole mattress might be a single compartir-rent and the lilling may be inserted therein in sections, even though the mattress may' be tufted' later..

The present apparati-isv is intended to till the mattress and permit the easy inserti-on. of one or more sections ot iilling material,l regardless of the mattress construction itself. The fill-ing' material, which may be either of fel-t, kapok, cotton, hair or'any' suitable material for the p.u1-'pose,is` compressed' in suitable molds Vof the desired size andV shape. These molds have been very clearly described a-nd specifically explained in my pri-or application, Serial` No.' 571,657, filed June 29, 1922, and each consi-sts preferably of sections 3 and 4 removably hinged together at one' end-as indica-ted at. 6y and having locking means- 5 at its other en -d to hol-d the charge of. filling material firmly compressed in pla-ce while handling the mold.y

Handlesv 7 are provided for tripping or releasing the moldvsections after-they have been inserted into the mattress casing, thereby partially relieving the compression of the mold sections onthe charge and permitting the ejection or removal. of' thet charge from the mold. I-

Plungers 8- are sli-dably arranged. Within th-c molds-and arev adapted toibear` against one end of the' charge 9Y therein- Obviously,

Awhen thel plunger is actuated' relative tothe mold after the mold sections have been released from interconnection either by movingy the moldor` moving the plu-nger .and tick, thechargewil-l be ejected from thel mold. In the machiner illustrated, the pluri-gers and tiek are moved While the molds are held.

A-stitfener or rein-toreine` stick l0 is generally arranged lengthwise et the mold so as to prevent any buckling or lengthwise compressing'ofvthe charge- |lhis stiilener k stick is moved together with the plunger and charge and may be removed-- from. the mattress after the mold itself has been removed ot the locked rvmolds iny unison; I have-.ar-

The mattress easing or tielt is arrana'ed on the table and its upper and lower free edges are secured to the fastening' pins if and the part 16, respectively.
